A patient asks the nurse why the infected area on his arm is so red. Which of the following should the nurse respond to this patient?
1. The body has increased the blood supply to the area.
2. Body fluids are leaking into the area.
3. White blood cells are trying to kill the infection.
4. The body is walling off the infected area to prevent it from spreading.
The body has increased the blood supply to the area.
Rationale: During the vascular phase of the inflammatory process, vasodilation occurs to increase the blood supply to the area, causing redness and increased warmth of the area. Body fluids leaking into the area would lead to edema. White blood cells trying to kill the infection would lead to pus formation. The body's walling off of the infected area is an activity seen in the cellular phase of the inflammatory process.
